This invention relates to anelectricalapparatus, particularly: tomountings for electric. currentimeters andthe switches and fuse blocksassociated I therewith, and has for its 1,- objecttheprovision of anovel paneliboard or device for this purpose which maybe set flush inthe wall of ahuildingand which will, moreover, be theft-proofso astoprevent unauthorized use of current or tampering with Harry: of theinterior mechanismby unauthorized or unscrupulous persons An importantandmore'specific object is the provision of a mounting. comprising. a

box-like casing adapted to-be let flush into a wall? and containing thefuse block and switch mechanism, the front of the. casing being closedby a cover whichprovidesa neat trim for'thebox and the. electric lightmeter used-in connection therewith, certain portions "of the cover beingcapable of removal by the employees or other authorized personsconnected with the electric light company,- the removal of theseelements, however, necessitatin taking off certain seals which areprovide by the company for its protection, it being quite obvious thatthe absence of these seals will be a clear indication that some one hasbeen tampering with the mechanism.

Another object is to rovide a device of -this character in which t ecover is provided with a door which may be readily opened by the user ofthe current so as to permit renewal of any of the fuses in case theybecome blown out as fre uently happens.

An additional ject is to provide a device of this character.which inaddition to being neat and attractive in appearance will be also simpleand inexpensive in manufacture, easy to install, positive in itsoperation, efiicient and durable in service and a general improvement inthe art.

With the above and other objects and advantages in view, the inventionconsists in the details of construction and the arrangement 45: andcombination of parts to be hereinafter more fully described and claimed,and illustrated in the accompanying drawings, in which Figure 1 is afront elevation of the complete device.

Figure 2 is a vertical section'taken on'the line 22 of Figure 1, and

Figure 3 is an elevation of the boxwith the cover removed.

Referring more particularly to the draw- 55: ings, I have shown thedevice'as comprising a box or casing constructed of any suitablematerial, preferably sheet metaland of any necessary size; This box orcasing; is adapted to be let into a wall so as to be flush 60 with thesurface thereof, and the front of the box is open and formedwith acontinuously extending flange 11 which provides an abutment for thecover or finish indicated-generally by the numeral 12. Located at thefront or open face of the box or casing-isan auxiliary box structure 13which is depressed inwardly as shown but which has its back wallportion"14 formed with spaced-slots 14 to permit access to fuses 15 mounted'inthev usualfuse block v16, it being, well known-that these fuses must bereplaced in case they become broken or burned out from any: cause.Within the auxiliary box structure 13 is a partition '17: defining :aseparate compartment l7 the back of: which isprov-ided with an opening18 permitting access to two=othen fuses 19 carried by the fuse block.Also located within the compartment 17 P is the controlrswitch 20 whichmay be of any-ordinary or preferred type and equipped with anoperatinghandle 21- which extends through a suitable slot 22 in the front closureplate-23- which isof'considerably greater length then the box 10 so asto have a portion 24iextendingupwardly thereabove as clearly indicatedin Figure '1. Securing members 25,- suchas: screwsor bolts pass throughthe frontplate 23and actto secure it together with the auxiL ilaryv boxmembers to the flange '11 of the box carrying wing nuts 31 tied togetherin pairs by rods 32 passing therethrough and carrying seals 33. Belowthe plate section 29 the plate 23 is formed with an opening 34 normallyclosed by a hinged door 35 which may be opened wheneverv it is necessaryto have access to the fuses 15. It is of course understood that the latesection 29 is removed when it is necessary to have access to themechanism of the switch and that the socket member 26 is removed when itis necessary to remove or repair the meter.

As an effective seal for the entire cover plate 23, I provide a stud 36which extends through a suitable hole 37 in the plate 23 and whichcarries a seal 38.

In use, the device isoperated in substantial-' ly the same manner asothers of this general class, but it will be observed that it is thefproof' owing to the provision of the seals and securing devices forthe'various removable elements. Furthermore, the device possesses thegreat advantage of being flush with the surface of the wall to which itis applied and it is therefore neat and attractive in appearance inaddition to having the other advantages specified. It is believed thatthe construction, operation and advantages will be readily apparent toone skilled in the art without further explanation.

While I have shown and described a preferred embodiment of theinvention, it should beunderstood that I reserve the right to make suchchanges in the form, construction and arrangement of parts as will notdepart from the spirit of the invention or the scope of the subjoinedclaims.

Having thus described the invention, I claim v 1. A cabinet for a flushtype panel board, comprising a rectangular box like casing having anopen front provided with an inwardly extended peripheral flange, thecasing being adapted tobe let into a wall with the open frontsubstantially flush with the face of the wall, and an auxiliaryfrusto-pyramidal shell member located within the open front of saidcasing and having a peripheral outstanding flange overlying said firstnamed flange, the

back portion of said auxiliary shell member being provided with spacedslots, said shell member dividing the space within the casing into twocompartments, access to the rear one of which may be'had through saidopenings, a partition element extending transversely of said auxiliaryshell member and dividing it into separate compartments one for fusesand the other for a switch, a panel for closing the front of the boxlike casing, said panel overlying the second named flange and securedthereto and to the first named flanges V by securing elements introducedfrom the front/and beingformed with a plurality of open1ngs,'and meansfor closing said openmgs in the panel.

' shell member being provided with spaced slots said shell. memberdividing" the space within the casing intoiforward and rearcompartments, fuse blocks located within the rear compartment andaccessible through said slots, a partition element extending across saidshell member and dividing said forward compartment into upper and lowersections, the back wall of the shell member within said upper sectionbeing formed with an opening, fuse blocks located within said rearcompartment and accessible through said last named opening, a switchdevice located within-said upper section, a panel overlying the front ofthe box and formed with openings permit ting access to said upper andlower. sections of the forward compartment, doors normally closing saidlast named openings, and securing elements passing through the panel andthrough said first and second. named flanges
